Imaging Studies III: Computed Tomography

893
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

3.5K
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

Summary
This summary is machine-generated.

Computed tomography (CT) of ball pythons can be performed in a curled position, reducing stress and scanning time. However, lung imaging may show variations in thickness and attenuation compared to traditional tube restraint methods.

Area of Science:

  • Veterinary Radiology
  • Reptile Imaging
  • Comparative Anatomy

Background:

  • Computed tomography (CT) in snakes often requires anesthesia and restraint, potentially causing stress.
  • Ball pythons naturally curl, complicating imaging procedures.
  • Alternative, less stressful imaging methods are needed for snake CT scans.

Purpose of the Study:

  • To compare the computed tomography (CT) appearance of ball python lungs in a curled position versus traditional tube restraint.
  • To evaluate the feasibility and potential differences in lung imaging parameters between these two positioning methods.

Main Methods:

  • Whole body CT scans were performed on ten healthy ball pythons in both curled and tube-restrained straight positions.
  • Curved multiplanar reformatted (MPR) images from curled scans were compared to standard MPR images from straight scans.
  • Lung attenuation and parenchyma thickness were measured at three cranial to caudal locations.

Main Results:

  • Positioning and scanning time was significantly shorter (12 ± 5 min) for curled snakes.
  • Mean lung parenchyma thickness was greater in curled images at locations 1 and 3 (P = 0.048, P = 0.044).
  • Mean lung attenuation at location 1 was significantly greater in curled images (P = 0.043).

Conclusions:

  • CT evaluation of ball python lungs is feasible in a curled position using curved MPR, offering a less stressful alternative.
  • Lung parenchyma thickness and attenuation may differ between curled and tube-restrained positions, requiring consideration during interpretation.
